Abstract: A highly reliable display device is provided. In a flexible display device including at least a first display region and a second display region, at least a portion of a wiring provided in the first display region or the second display region has a meandering shape or a chain-like shape. Since the wiring has a meandering shape or a chain-like shape, a short-circuit, a disconnection, or the like of the wiring due to curving or bending of the display device does not occur easily. The wiring having a meandering shape or a chain-like shape can prevent defective operation, lowered reliability, or the like of the display device.

Abstract: Provided is an apparatus and method for determining stereo disparity based on two-path dynamic programming and GGCP. The apparatus includes a pre-processing unit for analyzing texture distribution of an input image by using a Laplacian of Gaussian (LOG) filter and dividing the input image into a homogeneous region and a non-homogeneous region; a local matching unit for determining candidate disparities to be included in an each pixel of all pixels; a local post-processing unit for removing candidate disparities in a pixel of low reliability by performing a visibility test betweens candidate disparities in each pixel to improve the reliability of the candidate disparity; and a global optimizing unit for determining a final disparity for candidate disparities in an each pixel by performing a dynamic programming.

Abstract: A range finder device, for measuring, when a plurality of projected lights having radiation patterns whose light intensity differs three-dimensional space-wise are irradiated onto an object from a light source on a time-sharing basis to image-pick up reflected light of the projected light from the object with a camera, a distance using the light intensity of an image picked up, characterized in that, with respect to each of a plurality of surfaces including the center of the light source and the center of a lens, there is obtained, in advance, relation between an angle of each projected light from the light source and light intensity ratio in each surface, characterized in that, at the time of actual distance measurement, light intensity of each pixel of the camera is measured, and on the basis of the light intensity thus measured, and relation between the angle and the light intensity ratio on a predetermined surface corresponding to a coordinate position of the pixel measured, there is obtained the angle co

Abstract: A photoresist is applied to a first substrate made of glass or resin which has been subjected to alignment treatment. Next, the photoresist is exposed and developed by UV light so as to form a non-optical rotatory region in a stripe manner after a mask having a desired pattern is provided on the photoresist. Then, polymerized liquid crystal is applied or dropped on the substrate complex thus prepared so far after an alignment layer on the substrate is rubbed. Further, a second substrate whose surface has been subjected to alignment treatment is placed on the substrate complex such that the directions of the alignment of the two substrates are orthogonal to each other, and the substrate thus positioned is pressed against the substrate complex. Finally, the substrate complex is irradiated by the UV light to cure the polymerized liquid crystal so as to form an optical rotatory region, thereby completing an optical rotatory device.

Abstract: In the method, relatively inclined beams of light are projected towards the target from spaced locations at the station from which the distance to the target is to be measured. The locations are moved relative to one another along a linear path to bring the illuminated zones on the object together. The spacing of the locations then gives an indication of the distance sought to be measured. Apparatus for carrying out the method is also described.

Abstract: As is known, the walls in cavity structures often become quiescent only after a prolonged period. In order to detect whether and to what extent rock displacements can occur, measuring instruments are installed at mutually opposite points (I, II) on walls (W1, W2). A pendulum (1) mounted on gimbals carries a light source (5) at the mounting point and a light receiver (3) at the pendulum mass (2). On the opposite wall (W2), a mirror (4) is arranged at an inclination .alpha. relative to the vertical. A displacement of the mirror by T.sub.x or by T.sub.Z leads to an indication T.sub.Z at the light receiver (3).
